CHARLES BRUCKNER, OF NEW YORK, N. Y.

PETROLEUM INCANDESCENT BURNER.

SPECIFICATION forming part of Letters Patent No. 633,117, dated September 19, 1899.

Application filed September 20, 1897. Serial No 652,256. (No model.)

To all whom it may concern:

Be it known that I, CHARLES C. BRUCKNER, a citizen of the United States, residing at New York, (Brooklyn,) in the county of Kings and State of New York, have invented a new and useful Improvement in Petroleum Incandescent Burners, of which the following is a specification.

The'object of the present invention is to regulate with accuracy the discharge of petroleum vapors into a chamber wherein such vapors are commingled with atmospheric air and pass to a burner in which the blue flame, similar to a Bunsen flame, is employed to heat an incandescing mantle that is suspended in the flame.

The tapering needle-valve made use of by me is actuated from outside of the generat ing-chamber, so that a packing is not required for the rod of the valve, and the valve can tightly close the chamber when the lamp is extinguished, so as to effectually prevent any leakage, and the burner is constructed with reference to the'accurate proportioning of the air to the vapors and the thorough admixture of one with the other, so that the flame will only contain the proportion of hydrocarbon vapor necessary for obtaining the required heat.

In the drawings, Figure 1 is a vertical section through the generating-chamber and the two burners, and Fig. 2 is a vertical section at right angles to Fig. 1.

The liquid hydrocarbon is supplied by the pipe A from any suitable vessel, and this may be at a sufficient elevation for the liquid to run to the burner; but generally it is preferable to force atmospheric air into the supply vessel sufficiently to obtain the pressure required to carry the liquid to the place of combustion. This supply-pipe may be very small and passed through any suitable support or bracket B to the lamp.

The generating-chamber O is vertical and made in two parts separated by a partition 2, which passes from the bottom to near the top of the chamber, and the pipe A enters at the lower end at one side of the partition, and there is a valve-seat 3 at the lower end of the generating-chamber at the other side of the partition, such valve-seat being adapted to the long tapering needle-valve 4, which is passed up from below and receives motion from any suitable device, such as a rack 5 and pinion 6, actuated by a thumb-Wheel upon a shaft extending outside of the chamber D, and the guide 7 is adapted to support said rack as it is moved up and down. By this device the needle-valve can be raised to close the outlet from the generating-chamber perfectly tight, so that there will be no leakage, or the needle-valve can be Withdrawn to regulate the passage of vapor from the generatingchamber into the mixing-chamber D.

The hollow base of the lamp, within which is the mixing-chamber D, is extended laterally to form the hollow bases for one or two burners. I have represented two hollow burner-bases at E and E, and the partitions 8, that separate the mixing-chamber D from the burner-bases, extend to near the bottom of the burner-base, there being an opening or openings 9 for the mixed fluids to pass from the chamber D into the hollow burner-bases.

The incandescing mantles F F are to be of any desired character, usually a preparation of magnesia, and these are suspended above the'burner-bases E E in any desired manner. I prefer to use the bracket-arms 10, extending out from the sides of the generatingchamber 0 and received in the clamps 11, so as tobe raised or lowered according to the length of the incandescing mantles, and the movable rings 12 around the upper ends of the burner-bases serve to retain the distributing-plates 13, of perforated sheet metal, through which the fluids pass to the flames, and it is advantageous to apply screens at 14 15 in the hollow burner-bases and mixingchamber to aid in effecting a perfect admixture of the hydrocarbon vapors and the atmospheric air admitted into the mixing-chamber.

At the sides of the mixing-chamber are the air-inlet flues G, that are open at the bottom and communicate at the top through the openings 16 with the upper part of the mixing-chamber D, and the slides 17 within the air-inlet fiues can be raised or lowered and secured by screws passing through slots, so that the openings at 16 can be regulated for determining the proper volume of air to be admitted for mixing with the hydrocarbon vapors in the chamber D and from which chamber D such vapors pass down through the openings 9 and rise up within the hollow the generating-chamber tightly or to allow burner-bases and burn as blue or Bunsen the downward escape of thehydrocarbon Vft flames in rendering the mantles luminous. A small cup II upon the upper part of the mixing-chamber D and below the gen eratingchamber 0 is adapted to receive alcohol or similar fluid for heating the generating-chamber previous to lighting the lamp.

The bracket orsupport B is preferably hollow, as shown, and connected with the base of the lamp, and holes at 18 allow anyliquid to drop from the bottom of the mixing-chamber into the hollow bracket, and an opening at 19, with a screw-valve 20, allows for the withdrawal of any liquid that may accumulate in the bracket or support. This accumulation may sometimes arise from carelessness in handling the lamp, the intention being that the needle-valve 4 shall tightly close the generating-chamber when the lampis not in use and that suchvalve should only be opened the proper distance for allowing the escape of the necessary hydrocarbon vapors, the generating-chamber being maintained at a snfficiently high temperature by the adjacent burners for vaporizing the liquid passing by the supply-pipe A to such generatingehamber, so that the chamber will be full of hot vapors, and when the needle valve is closed such vapors will be retained and effectually prevent the risk of leakage of liquid when the lamp is not in use.

In consequence of the generating-chamber being closely adjacent to the flame it becomes sufliciently highly heated for the vaporiza tion of the liquid; but the valve-seat and valve at the lower end of the generatingchamber are not exposed to a high temperature and are not liable to become injured, and the metal is not exposed to such a high temperature as to vary the position of the valve in relation to the seat by expansion or contraction, and the mixing-chamber being immediately below the generating-chamber and the air-inlet flues extending upward and opening at the top into the mixing-chamber prevents the risk of the escape of vapors, be cause the jet or vapor issues downward from the valve-seat and carries with it the air, and the mixture is intimate, because the air and vapors escape from the lower end of the mixing-chamber into the hollow burner-base.
